Who has the range advantage on 2 4 7 rainbow?
Equities are close, but the monsters live in the Button's range: the Button has more overcard hands, and the Big Blind has four times the gutshots.
BTN vs BB single-raised pot: the button opens, the big blind calls.
dry / rainbow
Share of each range that is sets, two pair, overpairs, straights or better, and combo draws. This is who wins the big pots.
Equities are even, but the big pots run through the Button's range. Build them when the Button holds the goods and let the rest go cheap. Try swapping the lowest card for a middle connector and watch the edge move.
Neither range wants this flop, and that is exactly why the raiser keeps the edge. The button arrives with unpaired big cards, but the big blind is full of the same misses with worse backup, so the preflop lead survives contact.
